Abstract: The gasification unit includes a heat exchanger with a first circuit and a second circuit. The first circuit is in-line connection with an engine coolant; whereas the second circuit is in-line connection with an engine fuel line. The heat exchanger is used to capture heat from the first circuit via the engine coolant, and transfer said heat to the second circuit thereby heating up the fuel. The gasification unit is used to heat the fuel post fuel pump, but prior to being injected into the cylinder of an internal combustion engine. The heating of the fuel via the gasification unit improves the overall fuel economy of the internal combustion engine.
